This answerI your gave me no new info as I have seen 2 oncologists they both told me that there is no definitive info on this type of tumor so chemo is just a quess.
Decisions about adjuvant chemotherapy treatment are based on several factors including size of tumor, status of lymph nodes, the appearance of the cancer under the microscope, the presence or absence of hormone receptors for estrogen and/or progesterone, as well as HER2 status, the general health of the patient etc. Triple negative breast cancer means that ER and PR status are negative and that HER 2 neu status is also negative. Chemotherapy is recommended based on the tumor and the risk/benefit ratio. The risk of recurrence vs. risk related to side effects. This risk benefit ratio for your individual situation is best discussed with your oncologist who can discuss them in context of your individual situation. If you are concerned still have questions, a second opinion from a breast cancer oncologist is also a possible option for you.
